These tools have been designed to restrain and align pipes before and during the Electrofusion process. They work with pipes between 55mm and 250mm in diameter, those commonly used for mains installation. The pipe sits into a vee shape allowing all sizes of pipe to be held, including non-standard sizes. Reducers can be clamped by using a special reducer plate. Due to the wide vee cradle and the double strap holding, these tools are specifically good at aligning coiled pipes. The three way tool uses a special connector to allow elbows and tees to be held. These tools are completely adjustable making them versatile for every installation.
